I'm needing some help with this old Westclox alarm clock

So, I recieved this vintage 1930s-1950ish Westclox alarm clock from my dad years ago. The alarm will run perfectly as it scared me once when I was messing with it, but the clock itself has never worked. What do I have to do to fix this?

Never mind, I found out this is a wind-up one, and it works perfectly.
